US Patent 7938795 Bolus tip design for a multi-lumen catheter

A method of making a multi-lumen catheter includes forming a catheter body including a first lumen and a second lumen, and forming a catheter tip having a first channel terminating distally in a first opening on a first side of the catheter tip, and a second channel terminating distally in a second opening on a second side of the catheter tip opposite of the first side. The first and second openings of the catheter tip extend through an outer wall of the catheter tip to a dividing section. The catheter tip is affixed to the catheter body such that the first channel is aligned with the first lumen and the second channel is aligned with the second lumen.
